Green Tea Does Have Side Effects

By Tom Nelson


Daytime talk shows and health magazines are advertising tea as an excellent supplement for weight reduction. Because of the growing interest of tea, a lot of people are concerned about the safeness of the supplement. A majority of the press promoting the benefits of tea are usually not identifying enough of the unwanted effects. Fully understanding the potential unwanted effects is essential to be able to take benefits without having unwanted effects.

Like a lot of dietary supplements or prescription drugs, dosage has an important role when it comes to adverse effects. If taken without caution, even the most healthy supplement results in unanticipated reactions. Identical reasoning applies here. Just what exactly is the right amount of tea?

Among the most active ingredients of tea are caffeine and catechin. Both help with utilizing fat as the resource to generate energy which is known as thermogenesis. This process in return speeds up metabolic rate. Boosted metabolic function burns body fat faster in the body system.

There were countless experiments on caffeine and how it impacts human body. Lots of specialists are claiming in most cases more than 500mg of caffeine per day is too much. It could be unsafe causing unwanted effects which include insomnia, nervousness, restlessness, irritability, stomach upset, fast heartbeat and muscle tremors. Experts furthermore acknowledge that responsiveness to caffeine differs by an individual, however 300mg or below is considered a risk-free amount.

A cup of tea possesses around 20mg of caffeine. Compare to other caffeinated drinks, it is a small amount. In a single cup of coffee there are around 100mg of caffeine. When tea is the only caffeinated beverage taken then it should not be a concern. However if other caffeinated beverages are consumed throughout the day, then it is important to consider the overall daily amount of caffeine.

Scientists carried out tests related to the amount of tea. A daily dose of 800mg of EGCG has been successfully tested without any uncomfortable side effects. A cup of tea comes with roughly 100mg of EGCG, so that is 8 cups of green tea. Many clinical experiments suggest more EGCG means more weight loss, yet some professionals advise that too much of one compound from herbal plants can be a problem. It is not easy to come to a definite conclusion based on clinical tests, still many health specialists are stating 300mg of EGCG is a safe dosage to take in a day. There are successful lab tests with the dose of 300mg fighting cancer cells and weight reduction.

Due to the increasing use of green tea as a fat burning aid, even more laboratory tests are going to be done. For now, 300mg appears to be a safe amount for both EGCG and caffeine.
